UX Principles
Disability Spectrum
Disability isn't one fixed group. It can be permanent (one arm), temporary (a broken arm), or situational (holding a baby). Solve for one and you extend to many — the curb-cut effect: curb ramps built for wheelchairs also help strollers, luggage, and carts.
In plain terms
Disability can be permanent, temporary (a broken arm), or situational (holding a baby) — accessible design helps far more people than you'd expect.
Why this matters
Seeing disability as permanent, temporary, and situational shows accessibility isn't a niche concern — it touches nearly everyone at some point. The curb-cut effect means fixes for one group routinely help all.
